Setting up a frame

Hello everyone,

As you can see this is my first post and i was just wondering how you set up a JFrame with contained components.

Basically i want to have them in this order:

Canvas BELONGS TO: DesktopFrame (JInternalFrame).
JInternalFrame (ifrmTools) BELONGS TO: DesktopFrame (JInternalFrame).
DesktopFrame (JInternalFrame) BELONGS TO: dpDesktop (DesktopPane).
dpDesktop (DesktopPane) BELONGS TO: frmMain (JFrame).

But if you didnt understand that then i will try to break it down.

Basically i want to have a JFrame, that on it, has a canvas and an internal frame called ifrmTools. I want the Tools frame (internal frame) to float over the canvas so they can pick a tool to draw on the canvas with. Like a simple PAINT program.

Here is my issue, i have code, but it wont show the InternalFrame that is called 'ifrmTools' however it shows the Canvas.

Below is my code:

Code:

---

import java.awt.Canvas;
import java.awt.Color;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;

public class Create {
    private double currentVersion = 1.0;
    public JFrame frmMain = new JFrame("Welcome " + currentVersion);
    public JDesktopPane dpDesktop = new JDesktopPane();
    public JInternalFrame ifrmDesktop = new JInternalFrame();
    public JInternalFrame ifrmTools = new JInternalFrame("Tools");
    public Canvas cCanvas = new Canvas();

    public void createAll() {
        createAndAddCanvas();
        createAndAddToolsFrame();
        createAndAddDesktopFrame();
        createAndAddDesktopPane();
        createAndAddMainFrame();
    }

    public void createAndAddCanvas() {
        cCanvas.setBackground(Color.WHITE);
        ifrmDesktop.add(cCanvas);
    }

    public void createAndAddToolsFrame() {
        ifrmTools.setResizable(false);
        ifrmTools.setBounds(10, 10, 105, 250);
        ifrmTools.setVisible(true);
        ifrmDesktop.add(ifrmTools);
    }

    public void createAndAddDesktopFrame() {
        ifrmDesktop.setResizable(false);
        ifrmDesktop.setBorder(null);
        ifrmDesktop.setClosable(false);
        ifrmDesktop.setMaximizable(true);
        ifrmDesktop.setVisible(true);
        dpDesktop.add(ifrmDesktop);
    }

    public void createAndAddDesktopPane() {
        dpDesktop.setVisible(true);
        frmMain.add(dpDesktop);
    }

    public void createAndAddMainFrame() {
        frmMain.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frmMain.setSize(800, 600);
        frmMain.setLocation(100, 100);
        frmMain.setVisible(true);
    }

}

---

And obviously the main class calls this with a simple:

Code:

---

public class Main {

    public static void main(String[] args) {
        Create c = new Create();
        c.createAll();
    }

}

Thanks in advance,

You shouldn't mix AWT components with Swing components. So get rid of the Canvas and use a JFrame or similar instead. It does all that Canvas does and more. For your floating tools, why not just use a JToolBar?

e.g., toolbar tutorial

Ok man cool, cheers for the advice i really appreciate it.

Just out of consideration, howcomes you shouldn't mix them?

Oops, I meant JPanel, not JFrame above.
